Brief Summary:
This clinical trial is a single-site, 30 patient study for participants who have early stage retinitis pigmentosa, or Usher syndrome (type 2 or 3). Funding Source - FDA OOPD and Foundation Fighting Blindness.
Detailed Description:
This clinical trial is a prospective, randomized, double-masked, sham-controlled trial of 30 study participants who have early-stage retinitis pigmentosa, or Usher syndrome (type 2 or 3). The trial will be conducted at the University of California, San Francisco. Individuals with these diseases experience gradually worsening vision that ultimately may lead to blindness due to a genetic condition in which specialized cells in the eye's retina called photoreceptor cells cease functioning and/or die. The study is intended to use a relatively new, non-invasive technology called AOSLO (adaptive optics scanning laser ophthalmoscopy) in combination with a routine standard of care measurement called sdOCT (Spectral Domain Optical Coherence Tomography) to demonstrate that when a device that secretes an investigational drug called CNTF (Ciliary Neurotrophic Factor) is surgically placed in the patient's eye, one type of photoreceptor called "cone photoreceptors" is preserved such that the gradual loss of vision is halted.
